Separated bottom bed structure

ABSTRACT

A separated bottom bed structure mainly includes a front bottom bedplate, a rear bottom bedplate, reinforcing bars and screw handles; the structure is detached, separated and assembled through two hollow frames and an inverted U-shaped frame, allowing the front, rear bottom bedplates are kept equal in size, thereby being convenient for packaging and shipping. Furthermore, the screw handle includes a grip, screw head and button, where the button is used to separate the grip and screw head, allowing the grip to be adjusted to an arbitrary angle, thereby turning the screw head back and forth.

(a) TECHNICAL FIELD OF THE INVENTION

The present invention relates to a separated bottom bed structure, capable of being separated and flushed after detachment so as to be convenient for packaging and shipping.

(b) DESCRIPTION OF THE PRIOR ART

Conventional bottom beds are large in size and cannot be detached and separated, which are very inconvenient in packaging, shipping and handling

More advanced separable bottom bed structure is a bottom bed divided into a front bottom bed having projecting portions and a rear bottom bed having corresponding notches; the front and rear bottom beds are combined into a bottom bed by engaging the projecting portions with the corresponding notches.

However, the front bottom bed is rather protruding due to the projecting portions and therefore, unequal to the rear bottom bed in size such that they are still inconvenient in packaging and shipping.

SUMMARY OF THE INVENTION

The present invention proposes a separable bottom bed structure, a bottom bed of which can be detached, separated and assembled; it mainly includes a front bottom bedplate, a rear bottom bedplate, reinforcing bars and screw handles.

Upon assembly, more than one set of hollow frames and screw handles are respectively configured on the left and right corresponding ends of the central connection of the front, rear bottom bedplates, and an inverted U-shaped frame is configured between each set of left, right corresponding hollow frames, where the corresponding ends of the hollow frame and inverted U-shaped frame are respectively opened with a hole. Furthermore, the screw handle is engaged with a nut to lock the hollow frame and inverted U-shaped frame together after being passed through the corresponding holes, allowing the front, rear bottom bedplates to be combined into one bottom bed.

Furthermore, to increase the strength of the bottom bed, the two sides of the center of the bottom bed set are respectively configured with a reinforcing bar, the two ends of which respectively have an inverted U-shaped bent hook portion; the bent hook portions of the reinforcing bar are hung on fixing seats of the front, rear bottom bedplates, where a hole is respectively opened on the bent hook portion and fixing seat, a nut is positioned on the bottom bedplate below the fixing seat in advance, and a screw is passed through the corresponding holes of the bent hook portion and fixing seat from top to bottom to engage with the nut, allowing the reinforcing bar to be fixed to the center of the bottom bend, thereby preventing the sag of the bottom bed.

When the assembled bottom bed wants to be detached and separated, the reinforcing bars are first be detached down, and each screw handle 16 on the hollow frame is then loosened and the inverted U-shaped frame is taken out, allowing both the front bottom bedplate and rear bottom bedplate to be still kept equal in length and the fronts and rears thereof to be flushed, thereby achieving the convenience of packaging and shipping.

Conventional screw heads for fixing the bottom bed are larger in diameter so as to be convenient for a human's hand to turn. However, if the positions of screw holes are too close, two screw heads in engagement therewith will jam each other; the distance between the screw holes may be longer, but this will cause the bottom bed unstable. In addition, the screw head is inconvenient to be rotated by hand unless a tool is used.

According to the present invention, the screw handle mainly includes a screw head, grip and button, where the grip will be moved upward and separated from a tenon on the screw head when the button is pressed, while the grip can be rotated freely to an adjustment angle, and then recovered to its original position again and engaged with the tenon after the button is released, allowing the screw head to be driven to rotate at the same time when the grip is rotated. Therefore, the grip can be adjusted to an arbitrary angle and the screw head can be turned back and forth by using the button repeatedly when the grip is blocked, allowing the screw handle to be very convenient and practical upon locking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

First, referring to FIG. 1, which is a perspective view of the present invention, a general separable bottom bed set 1 is configured with a front bottom bedplate 10, a rear bottom bedplate 11, supports 12, electric cylinders 13 and linkages 14. One design focus of the present invention is in that: more than one set of hollow frames 15 and screw handles 16 are respectively configured on the left and right corresponding ends of the central connection of the front bottom bedplate 10 and rear bottom bedplate 11, and a inverted U-shaped frame 17 is installed between each set of left and right corresponding hollow frames 15 as FIG. 2 shows, where the corresponding ends of the hollow frame 15 and inverted U-shaped frame 17 are respectively opened with a hole 150, 170. Furthermore, a screw handle 16 is passed through each two corresponding holes 150, 170, and a nut 2 is then engaged therewith to lock the hollow frame 15 and inverted U-shaped frame 17 together as FIG. 3 shows, thereby combining the front bottom bedplate 10 and rear bottom bedplate 11 into one bottom bed.

Next, referring to FIG. 1 again and FIG. 4, another design focus of the present invention is in that: a reinforcing bar 18 is respectively configured at the two sides of the center of the bottom bed set 1 in order to increase the strength of the bottom bed, where the two ends of the reinforcing bar 18 respectively has an inverted U-shaped bent hook 180 hung on a fixing seats 19 of the front, rear bottom bedplates 10, 11, where a hole 1801, 190 is respectively opened on the bent hook 180 and fixing seat 19, and a nut 4 is configure on the bottom bedplate below the fixing seat 19 in advance as FIG. 5 shows. Furthermore, a screw 3 is passed through the corresponding holes 1801, 190 of the bent hook 180 and fixing seat 19 to lock them together with the nut 4, allowing the reinforcing bars 18 to be fixed at the center of the bottom bed, thereby preventing the sag of the bottom bed. When the assembled bottom bed wants to be detached and separated, the reinforcing bars 18 are first be detached down, and each screw handle 16 on the hollow frame 15 is loosened and the inverted U-shaped frame 17 is taken out, allowing both the front bottom bedplate 10 and rear bottom bedplate 11 to be kept still equal in length, thereby achieving the convenience of packaging and shipping.

Conventional screw heads for fixing the bottom bed are larger in diameter so as to be convenient for a human's hand to turn. However, if the positions of screw holes are too close, two screw heads in engagement therewith will jam each other; the distance between the screw holes may be longer, but this will cause the bottom bed unstable. In addition, the screw head is inconvenient to be turned by hand unless a tool is used.

Therefore, the action of the screw handle 16 is shown in FIG. 6. The screw handle 16 mainly includes a screw head 160, grip 161 and button 162, where the grip 161 will be moved upward and separated from a tenon (not shown in the figure) on the screw head 160 when the button 162 is pressed, while the grip 161 can be rotated freely to an adjustment angle as FIG. 7 shows, and then recovered to its original position and engaged with the tenon after the button 162 is released, allowing the screw head 160 to be driven to rotate at the same time when the grip 160 is rotated as FIG. 8 shows. Therefore, the grip 161 can be adjusted to an arbitrary angle and the screw head 160 can be turned back and forth by using the button 162 repeatedly when the grip 161 is blocked, allowing the screw handle 16 to be very convenient and practical upon locking.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
